Australian Twin Registry
'The Australia Twin Registry is a not-for-profit organisation which facilitates and supports medical and scientific studies that involve the participation of twins and or their relatives. These studies use the special characteristics of twins to enable questions of health and wellbeing relevant to Australians to be answered in ways that they otherwise could not. Members of the Australian Twin Registry are provided with information via letter regarding twin studies that they may be eligible for, and decides on their involvement. If the twin is interested in the study, they then fill in a response form which provides permission for the Australian Twin Registry to pass on their contact details to the research group running the study.
Twins of all types, of any age and in any state of health, are welcome to join the Australian Twin Registry. To register, or find out more, please call us on Freecall 1800 037 021 or register online'
